A Lightweight Hybrid Scheme for Hiding Text Messages in Colour Images Using LSB, Lah Transform and Chaotic Techniques

The advancement in information communication technologies has seen the rise in the deployment of various information exchange devices in the healthcare sector. Among these technologies is the Tele-care Medical Information Systems (TMIS) in which remote users can establish a connection with the hospital medical server and share the necessary information between them. This can potentially offer doctors and patients more reasonable treatment plan, as well as helping address the huge medical expenses and excessive medical treatment duration. There is therefore need to store patient data in the end devices, as well as transmit this data over public channels to facilitate decision making. This paper sought to review the security schemes that have been developed over the recent past to protect the patient data stored or transmitted in TMIS.

The adoption of electronic healthcare in hospital environment can potentially reduce costs and improve the quality of life of the patients. However, numerous security and privacy issues arise when sensitive patient data is shared among multiple devices and users. Owing to its vulnerable nature, electronic health records seem to be more attractive to attackers compared to other forms of records such as financial transactions. Consequently, the patient data collected at the sensors, transmitted across communication channels and residing in hospital servers is susceptible to various threats. The goal of this paper was to carry out a survey of the electronic healthcare environment and attempt to understand the various weaknesses that can be exploited. This is followed by some descriptions of the various preventive mechanisms as well as the noted gaps. Therefore, numerous recommendations are given that are deemed fit for enhanced security and privacy posture in electronic healthcare domain.

“…Based on radio-frequency identification (RFID), an authentication protocol for cloud environment is introduced in [51], while an anonymous authentication technique is proposed in [52]. However, these two schemes have high computation costs [53] at the tag side. Although the scheme in [54] can address this issue, it fails to protect against impersonation attacks.…”

The adoption of cloud computing has continued to grow, owing to its broad network access, remote accessibility, scalability, on demand self-service, rapid elasticity and resource pooling. In this environment, numerous devices are deployed to access the cloud data and services. This potentially increases the attack services, more so in public clouds. As such, the biggest challenge is the secure data exchange over insecure open network channels. This issue has seen the development of numerous security solutions over the recent past. In this paper, a survey of these security schemes, techniques and methods is provided. The findings indicate that majority of these methods have vulnerabilities that expose users to many attacks. Additionally, some of these security solutions have extremely high complexities that make the cloud communications inefficient.
